extra test modifications for D34158

[mibintc]

Summary

When adding support for D34158 which changes preprocessed output, I needed to make tiny test corrections for these. Adding the option -ffreestanding suppresses the new behavior, and that's the change I made to fix the tests.

[mibintc]

With the latest proposed fix for D34158, a few more test corrections are needed. The correction consists of suppressing the new preprocessor behavior. D34158 preincludes the file <stdc-predef.h> if the file is available.

[mibintc]

I need to redo the test changes. Will resubmit the diff.
